The mixing characteristics of industrial flotation columns were investigated using computational fluid dynamics (CFD). Particular emphasis was placed on the clarification relationship between liquid and solids parameters such as mean residence time axial dispersion coefficients. effects particle size bubble in column also studied. An Eulerian-Eulerian method applied to simulate multiphase flow,...

Introduction: The presence of antibiotics due to toxicity and sustainability as well as organic compounds as a combination of hard biodegradable wastewater is an undesirable issue in many industries. The aim of this study was to evaluate the efficiency of dissolved air flotation process for aniline and penicillin G removal from aqueous solutions. Methods: This was an empirical-lab study to w...

Flotation recovery in geometallurgical modelling is usually predicted based on relationships developed from batch flotation testing of different ore types. These batch flotation tests are usually performed at a constant set of operating conditions and at a fixed feed grind size P80. Usually the laboratory feed grind P80 is that which is expected to be produced in the full-scale flotation circui...

The removal of heavy metal ions from wastewater by sorptive flotation using Amberlite IR120 as a resin, and column, was investigated. A combined two-stage process is proposed an alternative the metals aqueous solutions. first stage sorption onto followed dispersed-air flotation. on depending contact time, pH, resin dosage, initial concentration studied in batch method .Various parameters such a...

In this study, the possibility of producing coal with less than 11% ash from tailings of flotation process was investigated. The effect of six flotation parameters: collector type, collector consumption, frother type, frother consumption, pulp density and mixing rate were studied on a sample from a tailing dam. A software based experimental design approach (DX7) was applied to determine and mod...

Due to its numerous and major industrial uses, graphite is one of the significant carbon allotropes. Refractories batteries are only a couple many uses for graphite. A growing market wants high-purity with big flakes. Since there fewer naturally occurring high-grade ores, low-grade ores must be processed increase their value meet rising demand, which predicted by >700% 2025 due adoption elec...

It is possible to obtain good performance from a flotation plant but it has proved difficult to maintain such performance. Recovery rates on a flotation plant can be around 90% and often lower, making flotation one of the least efficient processes in the concentration path. Hence, over the last few decades much research and development has gone into the stabilization and optimization of flotati...
